The XV306 is a multifunction expansion board that includes 4 Analog Input channels, 4 Digital Input channels and 4 Form A Relay Output channels. It provides a programmable input range on all Analog Input channels (+/-1 V, +/-2.5 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ +20 mA or +4 ~ +20 mA), and voltage and current outputs are jumper selectable. The Digital Input channels can be used as 32-bit counters. The XV306 also provides options for configuring power-on values for the Digital Output. 4 kV ESD protection and 2000 VDC intra-module isolation are also provided to enhance noise immunity capabilities in industrial environments.
